Abstract
The invention relates to the field of optical connectors, in particular to a small LC (local connector) plug which comprises a front shell and a rear shell. A pressure claw is arranged on the top of the rear shell, the rear shell and the pressure claw are of split structures, the pressure claw is fixedly clamped on the rear shell via a mounting seat arranged at the rear end of the pressure claw, and the rear end of the pressure claw is positioned at the rear of the rear shell. The small LC plug has the advantages that the rear shell of the small LC plug and the pressure claw are of the split structures, the pressure claw is fixedly clamped on the rear shell via the mounting seat arranged at the rear end of the pressure claw, the rear end of the pressure claw is positioned at the rear of the rear shell, accordingly, the length of the rear shell is not constrained by the mounting position of the pressure claw, and can be correspondingly reduced on the premise that the position of the pressure claw is unchanged when the small LC plug is manufactured, and the length of the LC plug can be reduced on the premise that the LC plug can be used with an existing socket.
Description
Technical field
The present invention relates to the optical connector field, particularly relate to a kind of small-sized LC plug.
Background technology
in the optical connector field, the development of LC plug is comparatively ripe so far, be that 201020550508.6 Chinese patent and application number are that 201110248703.2 Chinese patent just discloses respectively two kinds of multi-form LC plugs as application number, although the part difference is both arranged, but its chief component parts all comprise procapsid, back casing, LC contact pin (hereinafter to be referred as contact pin), afterbody sheath etc., wherein the tandem plug-in mounting of procapsid and back casing is fixed together, contact pin fixedly is assemblied in procapsid, the afterbody sheath fixedly is assemblied in the afterbody of back casing, the outside wall surface of procapsid is provided with the locking a brief period of time, the front end of the locking a brief period of time is positioned on procapsid, and the locking a brief period of time tilts to extend to the periphery of procapsid from front to back gradually, in addition, the middle part of the locking a brief period of time is provided with lock dog, the socket corresponding with the LC plug has jack, the hole wall of jack is provided with the locked groove corresponding with described lock dog, when LC plug and adaptive socket plug together, at first the locking a brief period of time is pressed down by the hole wall front portion of receptacle sockets, when LC plug and adaptive socket are pegged graft when putting in place, the locked groove of the lock dog of locking in a brief period of time in the receptacle sockets, thereby make locking a brief period of time resilience and making during its lock dog snaps in corresponding locked groove under himself resilient force, the LC plug is together with adaptive socket is locked in thus, when needs both during release, get final product by the projecting end (rear end) that presses down the locking a brief period of time, wherein for convenient, lower press operation is carried out in the locking a brief period of time, back casing is provided with the paw corresponding with the described locking a brief period of time, paw is for playing pawl, its rear end is positioned on back casing and extends towards the periphery of back casing from back to front, the front end of paw rides on the rear end of the locking a brief period of time, in the time of need to pressing down locking a brief period of time release, only need press the dynamic pressure pawl gets final product.
development along with the photoelectricity transmission technology, above-mentioned LC plug has obtained using very widely, but, under some special occasions, require the LC plug not only to possess original performance, and size, it is enough little to be mainly that length dimension can reach, yet the development of LC plug has been tending towards standardization so far, also standardization of matching used plug with it, how can keep the LC plug still can with the matching used prerequisite of existing socket under dwindle its size and become the comparatively problem of focus, as things go, can be used in conjunction with existing socket if think, its procapsid and the locking a brief period of time can not be changed, therefore, if wanting the size of dwindling the LC plug just can only set about from back casing and afterbody sheath.But in present LC plug, described paw and back casing are all to adopt integral structure (in two pieces of patent documentations enumerating as mentioned, the paw of disclosed LC plug and back casing are exactly one), therefore, for the position that guarantees paw and the position consistency of existing LC plug, the size of back casing also can't be dwindled.
Summary of the invention
The object of the present invention is to provide a kind of small-sized LC plug, to dwindle its length dimension under the prerequisite that the LC plug can be used in conjunction with existing socket.
In order to address the above problem, small-sized LC plug of the present invention is by the following technical solutions: small-sized LC plug, comprise procapsid and back casing, the top of back casing is provided with paw, back casing and paw are split-type structural, paw clamps by the mount pad of being located at its rear end and is fixed on back casing, and the rear end of paw is positioned at the place, rear of back casing.
In described mount pad and back casing one is provided with at least one pair of and is used for the elasticity holding claw of holding another tightly, and is opposed with a pair of two elasticity holding claw left and right.
Described elasticity holding claw is positioned at the place, the left and right sides of back casing.
The bottom of described mount pad is provided with the step surface relative with the rear end face of back casing, the front end of mount pad be provided with protrude to the left and right respectively, strut rail is at the blocking arm of elasticity holding claw front side, mount pad coordinates with back casing Anti-moving on fore-and-aft direction by step surface and the anterior blocking arm of its bottom.
The left and right sides of one in described mount pad and back casing is provided with opposed elastic card claw, and another is provided with the fit structure corresponding with described elastic card claw, and paw clamps by described elastic card claw and coordinating of hooking structure and is fixed on housing.
Also comprise the afterbody sheath, the afterbody sheath is provided with the bit architecture that allows that the mount pad that is used to paw steps down.
The described bit architecture that allows is be located at the slot to make way on the outside wall surface of afterbody sheath or formed by the vacancy position of cutting out on the outside wall surface of afterbody sheath.
Because back casing and the paw of small-sized LC plug of the present invention is split-type structural, paw clamps by the mount pad of being located at its rear end and is fixed on back casing, and the rear end of paw is positioned at the place, rear of back casing, thereby the length dimension that makes back casing no longer is subject to the restriction of paw installation site, therefore, can shorten the length dimension of back casing accordingly during fabrication under the prerequisite of the position that does not change paw, thereby dwindled its length dimension under the prerequisite that the LC plug can be used in conjunction with existing socket.
Further, after adopting elasticity holding claw structure, can adopt the mounting means of push-in type when the mount pad of assembling back casing and paw, accelerate the efficiency of assembling to the LC plug, in the time of between soon mount pad will push both from two elasticity holding claws, elasticity holding claw automatic tightening is " locking " mount pad also; Thickness due to mount pad in reality can not reach the thickness of back casing, and the place, the left and right sides that therefore the elasticity holding claw is positioned at back casing can shorten the length of elasticity holding claw accordingly, thereby guarantees its intensity and elastic force; Being step surface with described blocking arm can make elasticity holding claw and back casing one integrated mass as the front and back anti-shifting structure of mount pad, and the appearance of having optimized the LC plug is structural compactness; The bit architecture that allows on the afterbody sheath is also in order to increase the compactedness of product structure.
